I don't mind the new outlook. The meeting notifications are far less intrusive. You can update a meeting without spamming new emails. The simplified views do 95%of what I use it for. The calendar view is easier to read.

Everyone will hate this but whatever, internal company email is dead. It causes more issues than solutions. Phishing, spam, malware, etc. It's legacy tech.

The new outlook client is linking it with more modern medium specific communication such as loop, teams, sharepoint online, one drive etc.
